SPECIFICATION forming part of Letters Patent 310.319,471, dated June 9, 1885.

Application liled July 28, 1884.

To all whom it may concern: i

Be it known that I, JACOB ELMER, a citizen of the United States, residing at Biloxi, in the county of Harrison and State of Mississippi, have invented certain new and useful Improvements in Compound Spiling for Wharves and Bridges, of which the following is a description. 1

Figure l represents a plan view of compound spiling and fascines and anchors placed in position on the river-bank or in the harbor. Fig. 2 represents a front elevation of compound spiling and fascines in position in a Wharf. Fig. 3 represents separate and detached parts of the compound spiliug and the fascine.

In the accompanying drawings, a represents the first, principal, and foundation tubular cast-iron columns.

b represents the second and adjoining tubular cast-iron column.

c represents the third and adjoining tubu lar cast-iron column.

d represents the first, principal, and wooden spiling inserted in the first column, driven into the bed of the river or harbor, one half up inthe column, the other half or more driven into the bed of the river or the harbor bank for a foundation of the wharf or bridge.

c represents the second Wooden spiling inserted half in the rst cast-iron column, and the other half in the second cast-iron column, to join with the first spiling, so as to form one spiling and one column, and so on until the right height is reached.

f represents the third wooden spiling inserted in the second and third adjoining castiron columns, one half in each, the three adjoining spilings and columns to form the same as one spiling and one column, the sections of .which may be thus increased to any number.

g g represent in plan View fascines placed between and behind the columns for a foundation and protection to keep the bank from Washing and caving, and strengthen and hold the columns in their position.

h 7L represent sheet-anchor chains or iron rods to keep the columns steady and from leaning outward. Each may receive one or more anchors, according to the depth of water and height of the columns in the Wharf.

i lrepresent iron bands around the fascines.

(No model.)

jj represent blocks in the ends of the fascines. 4

k 7c represent iron shoes on the ends and points of wooden spiling for the purpose of protecting the end of the spiling in driving. The strength, size, and number of the compound spiles may be increased or diminished according to the requirement of the Wharf or bridge. rlhe smaller end of the second and adjoining column-section is to be inserted in the end of the rst, and each superadded section is to be similarly inserted in the upper end of that next below it, and so on until the needed height is gained. The upper end of the rst wooden spiling is to be driven tight into the rst column, so that the compound spiling can be hoisted and the wooden spiling remain fast in the iron column, and so on.

After the compound spiling is driven in the proper place and to the proper depth, and so that the foot end of the iron column and of the spiling rests on the foundation or bottom, for the purpose of steadying and bearing, the fascii'ies are to be placed on the bottom, alongside, and ou the inside'of spiling, and against the river-bank or beach, covered with small gravel and additional layers of fascines, and so on until the fascines reach above the Water. Then the fascines maybe coveredI with clay or mud. Vhen the depth of water requires more than one section of compound spiling, then at the joint of every section a metal band has to be fastened around the spiling, with a rod or chain attached thereto. The rod or chain is to extend to the bank and be attached to a sheet-anchor. The anchor is to be buried in the bank for the purpose of holding the compound spiling rmly tied to the fascines in an upright position, the faseines lying on the right and left and in the rear. The

metal band in front, connected with the rod or chain and anchor in the rear, will hold and keep the compound spiling in proper position against'any pressure of water or vessels. The fascines filled with gravel or small stones and properly placed against a caving or washing bank will stop all caving or washing and remain intact forever.

The compound spiles are to be 'driven to a proper depth, so as to hold almost any weight. The Wooden spiling in the iirst or bottom section is to extend out sufficiently beyond the IOO foot end of the first and bottom column, according to the quality of bottom of rivers or beaches. The rst or compound spiling is always to be driven so that the iron column will touch bottom, for steadiness and bearing and protection'against decay.

A wharf constructed according to this plan Y and. specification will remain intact and capable of use for many years. The fascines will keep the river-banks from washing and caving for all time to come.

The compound spiling will be an improvement in deep water for constructing Wharves and bridges, and can be built in most any depth.

l claim for compound spilingl. The combination, with iron tubular sectional spiling, of a sectional Wooden core entirely filling the iron sections, as set forth.

2. The combination, with iron tubular sectional spiling, of a Wooden core driven tightly into the lower iron section, part way th rough the same and partly projecting below4 the same, as set forth.

3. Iron spiling comprising tubes or sections, the lower end of each of which (except the lowest section) is inserted into the top of the section neXt below it, as set forth.

4. The combinationof the iron tubular sections of the sectional core, the said core-sections lling the interior of the iron sections, and breaking joints therewith.

5. The combination, with the spiling constructed as described, of the rods and anchors, substantially as described. Y

6. A wharf or river-wall composed of the spiling constructed as described, securedV by the described anchors and the fascine, as set forth.

JACOB ELMER.
